Along with the awful absorbed Amount i9-9900K, Intel arise this anniversary a new band of high-end desktop chips in the anatomy of Skylake-X Refresh and the 28-core Xeon W-3175X. Remember the 28-core processor? Yeah, the one Intel arise at Computex 2018 as actuality able of 5 GHz, except alone with what was after apparent to be alien cooling and a antic abstract motherboard.
At the time you ability accept apparent our commodity comparing Intel’s ambiguous 28-core audience to AMD’s advertisement of 32-core Threadripper, a absolute artefact that concluded up as the 2990WX. Ultimately, AMD’s processor was arise and it was a bit underwhelming in how it performs in some workloads, but the absolution did resemble carefully what AMD had arise at Computex.
So now let’s booty a attending at the final Intel Xeon 28-core CPU we’re about to receive. The Xeon W-3175X is based on the Cascade Lake architecture, accordant alone with Intel’s LGA3647 server socket, so those currently application X299 boards with the LGA2066 atrium can’t aloof bead in this new CPU after a abounding belvedere upgrade. The Threadripper 2990WX was absolutely accordant with AMD’s Atrium TR4 and X399 chipset, but Intel doesn’t accept the affluence of atrium affinity with their aerial amount calculation CPUs.
In agreement of specifications, the Xeon Platinum 8180 has 28 cores, 38.5MB of cache, 44 PCIe lanes absolute to the CPU, and six-channel DDR4-2666 anamnesis support, either ECC or standard. Sorry, did I say the Xeon Platinum 8180? Able-bodied I meant the Xeon W-3175X, which is a absolutely altered CPU of course.
The 3175X does beef things up a bit compared to the 8180 though, abnormally in agreement of alarm speeds. Intel’s absolutely altered and not at all the aforementioned server dent is clocked at 2.5 GHz abject with a addition up to 3.8 GHz, admitting the 3175X is clocked at 3.1 GHz abject and 4.3 GHz boost. This additionally agency a TDP access from 205W to 255W, not because this is basically an overclocked 8180, but because of some added reason, but I digress. It’s additionally absolutely unlocked, like all of Intel’s HEDT processors.
The key affair to agenda actuality is Intel’s 3175X is not clocked at 5.0 GHz, not as a abject clock, not as an all amount Turbo, and not alike as a distinct amount Turbo. And that’s, of course, because extensive 5.0 GHz on a 28 amount CPU is absolutely antic for archetypal operating conditions. Can the 3175X hit 5.0 GHz application alien cooling? Able-bodied probably, but afresh this brings us aback to Intel’s antecedent acknowledge of their 28-core HEDT chip: they showed it active at 5 GHz, affluence of websites gobbled that up after alike analytic it, and yet actuality we are, the absolute dent has been clearly released, and it doesn’t alarm anywhere a that mark.
Intel did arise out and apologized for not advertence that their audience complex an overclocked CPU, but that accomplished bureaucracy larboard me and abounding of you with a acerb aftertaste in your mouth.
Now a key aspect to the Xeon’s advertisement is that appraisement charcoal up in the air. Intel’s top end 18 amount Skylake-X Refresh CPU, which we’ll get into in a moment, costs $2,000 or so, while the Xeon Platinum 8180 costs a air-conditioned $10,000. Considering the Xeon W-3175X is basically a better, college clocked 8180, who knows what array of amount tag it will command. Will Intel amount it aloft the 8180? After a agnosticism it will be a very, actual big-ticket artefact and who knows how advancing it will be adjoin AMD’s 32-core offering.
And afresh there are the motherboards congenital to abutment this processor, which arise about banausic from what Intel acclimated at Computex. The Asus ROG Dominus Extreme has two 24-pin ability connectors, additional four 8-pin connectors, and two 6-pins, additional a aberrant VRM solution. It’s accessible all those connectors are aloof to facilitate overclocking the chip, but that still seems like a antic bureaucracy aback again, the 2990WX works aloof accomplished on X399 boards and can be overclocked after defective two 24-pin connectors. And while we don’t accept appraisement for the Dominus, you can bet it will be actual big-ticket to go forth with the 3175X.
So like we predicted at Computex, it seems like the 3175X is a business achievement and Intel’s attack to accept the world’s fastest single-socket CPU or article forth those lines, because it’s awful absurd that it will be a artefact account purchasing for the all-inclusive majority of buyers. Alike amid those cerebration of spending bags of dollars aloof on a workstation CPU, this 28-core barbarian will about absolutely be much, abundant worse amount than Intel’s LGA2066 articles or AMD’s Threadripper.
Moving on to Intel’s Skylake-X Refresh line, contrarily accepted as Basin Falls Refresh. What we accept actuality is a alternative of CPUs alignment from 8 cores and 16 threads, up to 18 cores and 36 threads, about replacing Skylake-X with agnate parts. The 6 amount i7-7800X doesn’t accept a absolute backup with this active line-up, instead the i7-9800X is an 8-core dent and it goes up from there.
So there’s a brace of absorbing things to agenda actuality blueprint wise. Nearly every allotment has accustomed a alarm acceleration boost, both to the abject and addition clock. The 18 amount i9-9980XE all-overs from 2.5 GHz abject and 4.4 GHz boost, to 3.0 GHz abject and 4.5 GHz boost, aural the aforementioned 165W TDP. Some chips accept abate bumps but about we’re seeing assets from 100 to 400 MHz. While the TDP isn’t a acceptable metric for ability consumption, the actuality the chips accept college abject clocks beneath the aforementioned TDP could advance bigger efficiency, possibly from accomplishment them on 14nm rather than 14nm . We’ll accept to analysis them to acquisition out.
Other absorbing things are all chips now accept a 165W TDP, ahead the 12 amount and lower were 140W, but now aggregate is the abounding 165W. L3 accumulation has additionally been bigger for the 12-core and lower CPUs, jumping from as low as 11 MB in the 8-core i7-7820X, to 16.5 MB in the i7-9820X. The 8-core additionally gets a abounding 44 PCIe lanes, ahead it was belted to aloof 28 lanes, and I’m academic this was done to accord bodies a acumen to buy it over the 8-core i9-9900K.
The added somewhat abnormal affair is the addition of a additional 10-core processor. It looks like this was done to accumulate the agency at seven SKUs, but with Intel ditching the 6-core, they’ve had to bifold up one SKU. So the abject archetypal 9800X is now 8 cores, the 9820X is 10 cores, and the 9900X resumes accustomed affairs at 10 cores as well.
Considering all Skylake-X Refresh chips are unlocked, you’d anticipate the higher-end 9900X wouldn’t be account affairs as it’s $100 added expensive, and alone gives you alarm acceleration boosts you could absolutely accomplish on the 9820X with overclocking. However the 9900X does affection added L3 accumulation which could arise in accessible depending on the workload; it won’t be a big accord for a lot of users, who acceptable will be bigger off with the 9820X, but there is at atomic one acumen to go for the 9900X instead.
With all of that out of the way, the best absorbing affair to agenda here, is that Intel hasn’t been advancing on appraisement whatsoever. They’ve absolutely abandoned AMD’s Threadripper platform, and gone with the exact aforementioned appraisement they acclimated for antecedent Skylake-X parts. The i9-9980XE is the aforementioned $1979 tray amount as the i9-7980XE for example, and that holds accurate for the blow of the line.
The alone potentially bigger amount artefact actuality is the $889 10-core i9-9820X, which offers a $100 extenuative on the 10-core i9-7900X, but that’s about it.
For example, AMD is currently affairs the 16-core Threadripper 2950X for $900, which is a abundant buy as a able workstation CPU able of administration best multi-core workloads with ease. Intel’s absolute adversary is still aloof a 10-core CPU, which the 2950X will calmly smoke in best workloads, admitting it’s the 14- and 16-core chips that will be abundant added competitive. Yet the 14-core is still priced at about $1400, $500 added than the 2950X, while the 16-core sets you aback a huge $1700.
AMD’s 32-core 2990WX which retails for $1800 will abide in antagonism with Intel’s 18-core i9-9980XE at $2,000. Neither of these chips are abundant amount buys, but afresh it’s absorbing that in the workloads area AMD’s multi-die architecture excels, like 3D modelling and rendering, Threadripper will still be alms abundant added achievement at a lower cost.
So a bit of a aberrant (or should we say arrogant?) barrage actuality from Intel. We accept new Skylake-X Refresh processors that don’t assume any added advancing adjoin Threadripper than the antecedent generation, with alone accessory alarm acceleration bumps at the aforementioned price, alongside a 28-core dent that will acceptable amount a candied affluence and requires a antic motherboard with endless of ability connectors. Hard to say if Intel would accept been bigger off artlessly befitting the aboriginal Skylake-X genitalia on the bazaar and giving it a amount cut and save themselves the engineering assets and be added advancing with AMD. But this is what we got instead.
